<The Reality of Cleaning> 1: Managing cleaning equipment and cleaning solutions is difficult. In the case of cleaning devices that utilize vibrational phenomena as a physical action, the low-frequency vibrational phenomena caused by the installation of the device, along with the device's inherent vibrational phenomena, and the vibrational phenomena of the objects being cleaned and tools interact with each other, resulting in a complex change in the vibrational state. In many cases where cleaning effects are observed, nonlinear vibrational phenomena occur. To confirm nonlinearity and manage it, logical learning and an understanding of vibration measurement are necessary. As for the chemical action of cleaning solutions, in devices that utilize cleaning effects, managing the concentration of detergents is important, but measuring the concentration distribution within the tank is a challenging situation. Various distributions change due to interactions with the environment, such as liquid temperature, humidity, air temperature, and atmospheric pressure. In particular, the distribution of dissolved gas concentration has a significant impact on chemical reactions, but no methods are known to achieve uniform dissolved gas concentration. (Using the diffusivity of fine bubbles is one method.) If detergents are added but only increase the variability of the concentration distribution, it will result in greater variability in cleaning results. ....

The Ultrasonic System Research Institute has developed a technology for ultrasonic <dynamic control> that optimizes the interaction of ultrasonic vibrations based on various analysis results of ultrasonic propagation states using an original ultrasonic system (sound pressure measurement analysis and oscillation control) and an abstract algebra model. Note: The control of resonance phenomena (low harmonics) and nonlinear phenomena (high harmonics) is achieved by setting oscillation control conditions based on a logical model. Compared to existing control technologies, this technique establishes and implements optimal control states tailored to the purposes of ultrasonic applications (cleaning, stirring, processing, etc.) through new measurement and evaluation parameters (note) related to the entire propagation path of ultrasonic vibrations, including various propagation tools. This is a method and technology that can be applied immediately, and we offer it as consulting services (there is an increasing track record of precision cleaning and stirring at the nano level). Note: Dynamic changes in the propagation state of tanks, transducers, target objects, and tools are measured, analyzed, and evaluated using original technology (ultrasonic testers).
